Hi, Ignite documentation describes how and when entry-based locks are obtained, both in atomic and transactional atomicity modes.
I was wondering why and when locks on data pages are required/requested -- PageMemoryImp.java shows that data pages have 8 bytes reserved for LOCK: https://github.com/apache/ignite/blob/15613e2af5e0a4a0014bb5c6d6f6915038b1be1a/modules/core/src/main/java/org/apache/ignite/internal/processors/cache/persistence/pagemem/PageMemoryImpl.java#L92 Thanks,
